===== Discussion =====
Hi, Can I have some help on how to use this plugin?
Can this be used for assigning keywords to headlines in a page, and then 'reproduce' these headlines when I performed the search using the keyword assigned to the headlines? 

It works. Very useful, thank you.

>Hi. Cannot download keywords.zip.
>Has location changed?
Nope, everything works pretty fine.  --- //[[ilya@lebedev.net|Ilya Lebedev]] 2008/11/07 11:37//

> Well, now I can download. But this zip contains nothing. 
It's really strange, but for me it contains the plugin.

>> This change seems a bit strange, because you just make a single "phrase" from the bunch of keywords. Probably it would be better skipping keywords explosion at all: ''%%{{keywords>nice film, horses, salt and pepper}}%%''  --- //[[ilya@lebedev.net|Ilya Lebedev]] 2008/11/07 17:21//

>>>I am not sure what you mean with explosion. Of course there should not be too much keywords.
>>>Here is another example:
>>> ''%%{{keywords>Wladimir Putin,Moskow}}%%''
>>> old way results in: ...content="Wladimir,Putin,Moskow"
>>>
>>> ''%%{{keywords>Wladimir Putin,Moskow}}%%''
>>> new way results in: ...content="Wladimir Putin,Moskow"

>>>>You've modified plugin code, by changing join symbol from comma to space. I suggest you removing ''join'' and corresponding ''explode'' at all.

Здравствуйте, Илья!
Я пока плохо во всём этом разбираюсь. Скажите, пожалуйста, куда надо эту строку с keyword вставлять? В любую часть текста?
